FIBER MATRIX SECRETS REVEALED
Additive values

be applied to fiber solubility and fermentability remains to
be seen. In addition, we must also quantify the effects of
various exogenous enzymes on solubility and fermentability, opening a whole new area of interesting research!

Whereas we know from research, experience and
chemistry that chemical values such as crude fiber are additive, we remain uncertain whether the same holds true for
biological values. For example, if we blend two ingredients
with different crude fiber concentration, we know that the
crude fiber concentration of the mix will be the weighted
average of the two. Whether this simple principle, which
is the cornerstone of least-cost feed formulation, can also

Sugar beet pulp
The extraction of juice from sugar beets leaves a pulp
with 10 to 15 percent dry matter that is frequently used in the
vicinity of the sugar factory as fodder for ruminants. If dried,

One notable aspect that fiber enthusiasts will soon observe by studying these data and any such similar information
is that there is no strong correlation between any of the values presented in this table.
